I am looking for guidance because I'd much rather use dry transfer chalk marks than decals. Though my car sides have a fresh flat Dullcote finish I cannot get my Clover House chalk marks to stick to?? the surface. Besides various hardness pencils, I've tried every suitable device in my arsenal with absolutely no luck. Sometimes, a part of the chalk mark sticks but then the other part doesn't come off the carrier paper. Is there a degradation of the adhesive with age? My dry transfer sheets are a few years old. What am I doing wrong?
